The instructions state to list the info "in the box below," but there isn't a box below (at least not on my computer). I didn't submit the info because there didn't appear to be anywhere to put it.

If I remember correctly, it is a bit confusing. But you put all that info in on the next page once you click Join group. So what I did was have two pages open. One with the initial page showing what info needed to be put in and then opened the "Join group" page in another tab.

Another way to do it would be to write down what you need to know so that you can remember what you need to put in the box on the next page.

Yeah, you have to squeeze it all into the little "reason for request" box. I put my name, address, phone number, and a link to my secondary feedback source just all in a row, and got approved in 48 hours.
